SPECIFICATION forming part of Letters Patent No. 722,717, dated March 17, 1903.

Application led August 18, 1902.

To all whom t may concern.-

Be it known that I, ADAM S. KIEFER, a citizen of the UnitedStates of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Steam-Generators or Vater-I-Ieaters; and I .hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in steam-generators or Water-heaters.

This invention pertains more especially to a generator or heater of the character indicated, which comprises a centrally-located vertically-arranged pipe; circular duid-circulating sections surrounding the said pipe and arranged at different elevations,respectively;

washers embracing the said pipe and snugly interposed between the adjacent fluid-circulating sections; two apertures formed in opposite sides, respectively, of the said pipe centrally of each fluid-circulating section and forming the duid-inlet and the fluid-outlet, respectively, of the said section, and a bar arranged within and extending longitudinally of the said pipe from the bottom of the lowermost duid-circulating section to the top of the uppermost fluid-circulating section and provided between the fluid-inlet and the Huidoutlet of each fluid-circulating section with a partition-forming member which extends diagonally of the interior of the said pipe from the bottom of the said outlet to the top of the said inlet and snugly fits Within the said pipe and obstructs direct communication between the said inlet and the said outlet and causes any water or uid which passes upwardly within the pipe below the said partition to impinge against the under side of the said partition and be directed by the partition to the inlet of the said fluid-circulatin g section through which the fiuid circulates and passes through the outlet of the said section up the upper side of the said partition toward the fluid-inlet of anyfluid-circulating section arranged next above. c

The object of this invention is to improve the circulation of the hot water or steam through the heater and to cause the iuid to be uniformly distributed in the passage-ways or chambers formed in or by the duid-circulating sections of the heater during the pas- Serial No. 120,122. (No model.)

sage of the fluid through the heater, so as to more thoroughly cleanse the said chambers or passage-Ways and maintain the heater in a vvclean lcondition internally.

invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a side elevation, mostly in section, of the fluid-circulating portion of a steam-generator or water-heater embodying my invention. Fig. II is a central vertical section on line II II, Fig. I, looking in the direction indicated by the arrow. Fig. III is a top plan in section on line III III, Fig. I.

The Water-circulating portion of Ia steamgenerator or water-heater embodying my invention is composed of a series of circular cast-metal sections co'mpactly arranged, re-

spectively, in a horizontal plane at dierent varranged web b.

A vertically-arranged pipe C extends centrally through the sections A and through the webs b of the sections B, centrally between the ends of the said webs. The pipe O eX- tends, therefore, centrally through the chambers ct of the sections A and divides the interior of the web b of each section B into two passage-ways b and b2, formed by and within opposite end portions, respectively, of the said web and arranged at opposite sides, respectively, of the said pipe, which passage-Ways communicate directly with the chamber or passage-way b3, formed by and within the chamber having the said web.

The pipe C interior-ly of each duid-circulating section is provided with two lateral holes or apertures O and C2, which are arranged directly opposite each other, and, as will hereinafter appear, the said aperture C forms a fluid-inlet of the said section and the ICO said aperture C2 constitutes the fluid-outlet of the said section. The apertures C' and C2 interiorly of each section B communicate with the passage-ways b and b2, respectively, formed interiorly of the web Z2 of the said section.

The iluid-inlet-forming apertures C' for all of the huid-circulating sections A and B are arranged in line vertically at one side of the pipe C, and the fluid-outlet-forming apertures C2 for the said sections A and B are arranged in line vertically at the opposite side of the said pipe.

The pipe C is adapted to be connected at its lower end with the water-supply pipe, (not shown,) and consequently the said end of the said pipe forms the water-receiving end of the pipe.

The upper end of the pipe C is adapted to be connected with a fiuid-distributing-pipe system, (not shown,) and consequently the said upper end of the said pipe constitutes the fluid-outlet of the pipe.

The sections A and B are clamped together and preferably each of the said sections is provided at the top with an upwardly-projecting annular ange 5, snugly embracing the pipe C, and has another annular flange 6, projecting downwardly from its bottom and snugly embracing the said pipe. A washer e embraces the pipe C between the adjacent flanges 5 and 6 of adjacent sections A and B. The pipe C above the upper flange 5 of the uppermost fluid-circulating section and below the lower flange 6 of the lowermost fluidcirculating section is screw-threaded externally, and correspondingly-threaded nuts G are mounted upon the saidthreaded portions of the said pipe, and washersf are interposed between the said nuts and the said fluid-circulating sections, and obviously all the sections A and B are clamped together upon tightening the said nuts.

Within the pipe C is arranged a bar R, which is preferably a metal casting and extends longitudinally of the said pipe from the bottom of the lowermost duid-circulating section to the top of the uppermost Huid-circulating section. The bar R is shaped and arranged as required to form centrally of each fluid circulating section a diagonally arranged partition fr, which extends from next below the fluid-outlet of the said section diagonally and interiorly of the pipe C to the top of and above the duid-inlet of the said section and snugly fits the said pipe internally. The bar R, between adjacent partitions r, is shaped as required to form a at web R', which connects the upper portion of the lower of the said partitions with the lower portion of the upper of the said partitions, which web is arranged edgewise between the fluid-outlet next above the lower end of the said lower partition and the duid-inlet next below the upper end of the said upper partition. It will be observed, therefore, that a partition r is formed upon the bar G between the duid-inlet C and the duid-outlet C2 of Veach fluid-circulating section and prevents direct communication between the said outlet and the said inlet and that the said partition directs the fluid discharged through the said outlet upwardly toward the fluidinlet of the fluid-circulating section next above and that a web arranged between the said lpartition and the partition next above divides the lluid passing upwardly to the lastmentioned fluid-inlet, so that the fluid discharged into each fluid-circulating section A `is effectually distributed between opposite sides, respectively, of the chamber a of the said section, and the iiuid discharged into the passage-way b of each fluid-circulating section B Vis effectually distributed between opposite sides of the said passage-way, and is consequently distributed at the outer end of the said passage-way between opposite sides, respectively, of the chamber b3 of the circular chamber of the said section B.

The bar R is provided at the lower side of the partition r, arranged between the fluidinlet and the fiuid-outlet of the lowermost fluid-circulating section, with a flat vertical portion R2, which is arranged edgewise relative to the said fluid-inlet, and consequently divides the water passing through the said inlet between the opposite sides of the passage-way b of the said lowermost section.

The bar R is provided above the upper por- Ition of the partition r, arranged between the fluid-inlet and the fluid-outlet of the uppermost fluid-circulating section, with a flat vertical portion R3, which is arranged edgewise to the said outlet and divides the fluid discharged through the said outlet between opposite sides, respectively, of the upper end of the pipe C.

It will be observed that the component parts of my improved steam-generator or waterheater are readily assembled, that the construction is simple and durable, that the fluid is uniformly distributed in its passage through the heater, that the uid circulates rapidly through the heater, and that the said rapid circulation and the aforesaid uniform distribution of the duid maintains the interior chambers or passage-ways of the water-circulating sections in a clean condition.

The bar R is secured in position in any approved manner, so that it cannot become dis- IOO IIC
